Plasma Physics of the Local Cosmos


Book Description

Solar and space physics is the study of solar system phenomena that occur in the plasma state. Examples include sunspots, the solar wind, planetary magnetospheres, radiation belts, and the aurora. While each is a distinct phenomenon, there are commonalities among them. To help define and systematize these universal aspects of the field of space physics, the National Research Council was asked by NASA's Office of Space Science to provide a scientific assessment and strategy for the study of magnetized plasmas in the solar system. This report presents that assessment. It covers a number of important research goals for solar and space physics. The report is complementary to the NRC report, The Sun to the Earthâ€"and Beyond: A Decadal Research Strategy for Solar and Space Physics, which presents priorities and strategies for future program activities.




Interaction Of Electromagnetic Waves With Electron Beams And Plasmas


Book Description

The interaction of electromagnetic waves with matter has always been a fascinating subject of study. As matter in the universe is mostly in the plasma state, the study of electromagnetic waves in plasmas is of importance to astrophysics, space physics and ionospheric physics. The physics of electromagnetic wave interacting with electron beams and plasmas also serves as a basis for coherent radiation generation such as free electron laser and gyrotron and advanced accelerators. This monograph aims at reviewing the physical processes of linear and nonlinear collective interactions of electromagnetic waves with electron beams and unmagnetized plasmas.

High-Power Laser-Plasma Interaction


Book Description

The field of high-power laser-plasma interaction has grown in the last few decades, with applications ranging from laser-driven fusion and laser acceleration of charged particles to laser ablation of materials. This comprehensive text covers fundamental concepts including electromagnetics and electrostatic waves, parameter instabilities, laser driven fusion,charged particle acceleration and gamma rays. Two important techniques of laser proton interactions including target normal sheath acceleration (TNSA) and radiation pressure acceleration (RPA) are discussed in detail, along with their applications in the field of medicine. An analytical framework is developed for laser beat-wave and wakefield excitation of plasma waves and subsequent acceleration of electrons. The book covers parametric oscillator model and studies the coupling of laser light with collective modes.




Strongly Interacting Matter in Magnetic Fields


Book Description

The physics of strongly interacting matter in an external magnetic field is presently emerging as a topic of great cross-disciplinary interest for particle, nuclear, astro- and condensed matter physicists. It is known that strong magnetic fields are created in heavy ion collisions, an insight that has made it possible to study a variety of surprising and intriguing phenomena that emerge from the interplay of quantum anomalies, the topology of non-Abelian gauge fields, and the magnetic field. In particular, the non-trivial topological configurations of the gluon field induce a non-dissipative electric current in the presence of a magnetic field. These phenomena have led to an extended formulation of relativistic hydrodynamics, called chiral magnetohydrodynamics. Hitherto unexpected applications in condensed matter physics include graphene and topological insulators. Other fields of application include astrophysics, where strong magnetic fields exist in magnetars and pulsars. Last but not least, an important new theoretical tool that will be revisited and which made much of the progress surveyed in this book possible is the holographic principle - the correspondence between quantum field theory and gravity in extra dimensions. Edited and authored by the pioneers and leading experts in this newly emerging field, this book offers a valuable resource for a broad community of physicists and graduate students.




The Interaction of Strong Electromagnetic Fields with Plasmas


Book Description

The range of plasma conditions considered here is intentionally broad, systematic and relevant to such areas as plasma heating, plasma acceleration, laser-plasma interaction, and plasma confinement. This volume presents the principle concepts of plasma physics - with an account of the linear theory of electromagnetic wave interaction - and then covers nonlinear processes with extensive treatment of the pondermotive force. Related experimental work is thoroughly reviewed.




The Dissipation of Electromagnetic Waves in Plasmas


Book Description

This anthology includes articles on experimental studies of the interaction of high-power electromag netic waves with collisionless plasmas and with electrons. The nonlinear interaction of waves with plasmas has been investigated both under free space conditions and in waveguides. A study of secondary-emission dis charges was made in order to ascertain their possible effect on measurements in waveguides. The results presented here on the interaction of high-power waves with plasmas and electrons are of interest to a wide range of physicists and engineers concerned with various questions on the interaction of electromagnetic radiation with plasmas, including microwave heating of plasmas and laser fusion. v CONTENTS An Experimental Investigation of Nonlinear Dissipation of Electromagnetic Waves in Inhomogeneous Collisionless Plasmas - G.M.
